Phenolic compounds are important components of grapes and wines. They have been found
to have important roles in grape and wine systems and properties that are beneficial for human
health. Vanillin (3-methoxy-4-hydroxy ...

The effects of sample solvent composition and the
injection volume, on the chromatographic peak profiles of two
carbamate derivatives, methyl 2-benzimidazolecarbamate (MBC)
and 3-butyl-2,4-dioxo[1,2-a]-s-triazinobenzimidazole ...

Impurity free eluission spectra of HCCCHO and DCCCHO have
been rephotographed using the electronic-energy-exchange method
with benzene as a carrier gas. The near ultraviolet spectra of
ReeCHO and DCCCHO were photographed ...

Calculations are performed on the \S <:Jd ground states of
d ' +
the H and HC) molecules using a basis set of non-integral
~ ~ I
elliptical orbitals. Different variational wavefunctions constructed
i- for H~ involved ...

Exch~nge energy of the He-He system is calculated using
the one-density matrix which has been modified according to
the supermolecular density formula quoted by Kolos. The exchange
energy integrals are computed analytically ...

Reactions of the boron halides with organic halides
and organo-silicon compounds have been investigated. The
results show exchange of halogens between the BX3 (X = Br# 1)
and the organic halidef exchange of the halogen ...

The use of theory to understand and facilitate catalytic enantioselective
organic transformations involving copper and hydrobenzoin derivatives
is reported. Section A details the use of theory to predict, facilitate, ...

Both El MS and FAB MS behavior of two groups of compounds, aryltin and
ferrocene compounds, have been studied.
For the aryltin compounds, the effect of substituent group position, substituent
group type and ligand type ...

A number of metal complexes containing the ligand
5,5,7,12,12,14-hexamethyl-l,4,8,11-tetra-azatetradecane were
synthesized and analyzed using electron impact (EI) and fast atom
bombardment (FAB). The FAB mass spectra ...

In order to investigate the use of Fast Atom
Bombardment Mass Spectrometry (FAB-MS) as a tool for
structural characterization, two groups of complexes are
analyzed. The first group is a set of ruthenium(II)
coordination ...

The objective of this thesis was to demonstrate the
potential of fast atom bombardment mass spectrometry (FABMS)
as a probe of condensed phase systems and its possible uses
for the study of hydrogen bonding. FABMS was ...

A flow injection hydride generation direct current plasma atomic emission
spectrometric (FI-HG-DCP-AES) method was developed for the determination of lead at
ng.ml-l level. Potassium ferricyanide (K3Fe(CN)6) was used ...

A fluorescence excitation spectrum of formic acid monomer
(HCOOH) , has been recorded in the 278-246 nm region and has
been attributed to an n >7r* electron promotion in the anti
conformer. The S^< S^ electronic origins ...

The successful development of stable biosensors incorporating entrapped proteins
suffers from poor understanding of the properties of the entrapped biomolecules. This
thesis reports on the use of fluorescence spectroscopy ...

ZnF2, CdF2, and CUF2 have been adsorbed onto the surface
of montmorillonite K10, and the infrared and 19F, 27 AI, and 29Si MAS
